Undersea Arctic Rocks Resemble Those in the Southern Hemisphere
08.05.2008
Scientists have found volcanic rocks under the Arctic Ocean having the same particular geochemical signature as rocks in the southern hemisphere. This discovery re-opens an underlying debate concerning the origin of such formations.

Synthetic Pesticide Levels in Antarctic Penguins Present a Complex Mystery
06.05.2008
For the past 30 years, DDT (Dichloro-Diphenyl-Trichloroethane synthetic pesticide) derivatives have persisted in Antarctic penguins at a constant level, and researchers say glacial meltwater may be the source.

Caribou as Indicator of Climate Change
06.05.2008
Fewer caribou calves are born and more are dying in West Greenland. A recent study conducted by Eric Post, from Penn State University in collaboration with Mads Forchhammer, from the University of Aarhus in Denmark, shows that the timing of peak food availability no longer corresponds to the caribou's calving…

Melting Sea Ice
05.05.2008
The September 2007 record low minimum extent of the Arctic sea ice could be broken this fall for the third time in five years. According to the calculations of scientists from the University of Colorado at Boulder, the minimum extent of the Arctic sea ice has a three-in-five chance of…

ADRILL Cores to Be Analysed at Florida State University
30.04.2008
The sediment cores extracted during the ANDRILL project (Antarctic Geological Drilling) are now stored in the "cold room" at Florida State University to be studied. Through the analysis of these cores extracted from deep beneath the sea floor of Antarctica's western Ross Sea, scientists hope to gain new insight into…

Effects of Climate Change on Arctic Marine Mammals
30.04.2008
Published in the Ecological Applications of the Ecological Society of America, a new study entitled "Arctic Marine Mammals and Climate Change" estimates hooded seals, polar bears and narwhals to be the most at-risk mammals of the Arctic.

Ice Coring in Alaska
30.04.2008
A new multi-year ice coring mission is being carried out in Alaska's Denali National Park, bringing together the University of New Hampshire and University of Maine. This year's month-long reconnaissance mission will aim to identify the best possible drill sites to recover ice cores from the park's glaciers.

Polarized Northern Lights Detected in the Arctic
29.04.2008
An international team of scientists, lead by Jean Lilensten of the Laboratory of Planetology of Grenoble in France, has detected polarization in aurora borealis. This unexpected finding could provide new insight on the composition of Earth's upper atmosphere, the configuration of its magnetic field and the energies of particles coming…

Ozone Hole Recovery Could Modify Southern Hemisphere Climate
29.04.2008
Scientists from the University of Colorado at Boulder, the National Oceanic and Atmospheric Administration and National Aeronautics and Space Administration claim that if the stratospheric ozone hole were to recover, the southern hemisphere's climate, including that of Antarctica, could be subject to big change.
